HP Omen 870-244 100% HD access at boot time. Takes more then 5 minutes to boot fully.

Question1: When I boot it takes about 2 minutes before I can access Task Manager and then in there HD is at 100%  and it stays this way for about 5 minutes.  I installed all the updates for it from the HP tool but it is still slow to boot. Is there something that  I am missing that I need to do to fix this?

Question 2: I also can not figure out how to get into the BIOS on this machine. None of the normal keys seem to get me in. 

Question 3: How do I find the information on the Motherboard to see it it will support a NVME  SSD.

To answer the questions

1) The slow boot time and hard drive activity could be normal but it could also mean the hard drive is starting to fail.  Since it still boot up, then now is the time to fix it before it fails.

2) To get into the BIOS on the HP, start tapping on the Esc key before pressing the start button.  Keep tapping Esc and then press the start button.  There should be a popup menu with a choice to enter the BIOS from that popup menu

3) To find info about the possibility of NVME SSD.  I went to Crucial.com
